Christina did phenomenally! She rocked Idol! "You Lost Me" was a good choice. I was so excited when the Idols came out so sing "Beautiful," then turned it up a notch with "Fighter," and BAM! There she was! I couldn't stop looking at those pretty blue eyes.

i practically have watched all the youtube uploads of Christina's performance in A.I tonight! It's about 20 times all in all~! Can't get enough of it! Awesome! Amazing! Fantastic! Incredible! and so much more!

Awesome voice! versatile and flawless! No one could sing like her! this is Christina like we have never heard her before! What a bold move to sound different always in each album and explore other worlds (musically speaking). I love you Christina! no matter what they say!

ove her performance!!! awesome! i am happy she chose to sing the song! I have just heard the snippet before but i knew then that it's going to be one of my favorites in her album! Amazing album! all songs are great! <3

Christina's songs always speak to me but last night's performance shocked me - she must have a camera in my home. The song is exactly how i'm feeling and what i'm going thru right now! Thank you Christina for helping me express my feelings!! xoxo

i really loved the performance... but i was missing something... i hope you i'm wrong but i think after her pregnancy her voice got ugh.. i dont know.. i think her voice somewhat changed.. i hope you'll consult a vocal coach just to make sure nothing is wrong with your voice. love lots.

that was so beautiful, it give me a goosebumps since beautiful! Christina u kill that performance on american idol to let the whole world know that u still have that powerful unique voices out there that no one could compare to u!! amazing!!!!!

I just saw it because I had to work. OMG I am AMAZED. How can you keep getting better?? Beautiful performance!!I am telling you that chorus with the things you do with your vocals. The whole performance passion, emotion evoking, and OUTSTANDING!! The Queen X
